Set during World War II, scientist Dr. John Russell is sent to Berlin on an undercover mission to investigate the Nazi's interest in an experimental uranium bomb project. He is no trained spy however, so he is accompanied by British MI6 agent Peter Graham, and later Anne Taylor. Next to the main storyline, Russell will also need to find out if his companions are pursuing their own agenda.

This 3D adventure with pre-rendered backgrounds is entirely mouse-driven with a point-and-click interface. The left mouse button moves Russell around and is used to examine objects. The right mouse button is used to pick up or use items. Pressing the latter twice makes the character run. Puzzles consist of researching articles, item combinations, but also mechanical systems and broader puzzles, such as piecing a torn letter together. The game includes a beginner's mode, where pressing a key highlights all important objects in the area.

Optionally, the player can choose to play the entire game with a sepia filter, rendering the images a more authentic and historical feel.
